Hi,
I was trying to compile and run a program using OpenCL on the development board running Ubuntu. The OpenCL API reports one platform with one device. clCreateContextFromType returns this device when a CL_DEVICE_TYPE_GPU is requested.

However, the OpenCL program compiles and executes, it runs on one core of the CPU and achieves exactly the same number of operations per second as the same algorithm using ARM Advanced SIMD extension (Neon). So I want to ask if there is really a GPU on the chip, and if it is, how can I make it work?
